Answer:
The correct answer would be option D) no gametes.
Explanation:
The ABC model of the flower was formulated to describe the collection of genetic procedures that determines floral organs in several plants. These species consist of four whorls which are sepals, petals, stamens, and carpels. These whorls are expressed by the expression of a number of genes present in each whorl or verticli.
Gene A is solely responsible for the sepals while the co-expression of A and B genes are responsible for the petals. The identity of the stamens is expressed by B and C and the carpels require C and D genes to be active.
The homozygousity for a normal mutation in gene C will lead to inactive or lack stamens and carpels, which are male and female reproductive organs. These are an important structure for forming gametes.
Thus, the correct answer would be option D) no gametes.
Answer:
Correct
Explanation:
The statement is correct because, during the chemical synapses, the transmission of information takes place when the presynaptic neuron releases a <u>neurotransmitter</u> that binds to a specific receptor located in the postsynaptic membrane. The release of these neurotransmitters happens almost always when the action potential reaches the synaptic terminal. In the membrane of the synaptic terminal, the number of Ca++ voltage-depended channels is greater than in other parts of the membrane, hence, when the action potential depolarized the membrane, the channels open and the Ca++ defuses actively into the cell. The intracellular concentration of Ca++ is very high and this strong and rapid increase, facilities the depolarization of the membrane and <u>allows the release of the neurotransmitter to the postsynaptic membrane</u>.

<h3><u>Answer</u>;</h3>
B. 2 molecules of ATP are used and 4 molecules of ATP are produced.
<h3><u>Explanation</u>;</h3>
- Glycolysis is the first phase of ecllular respiration that converts one six-carbon molecule of glucose into two three-carbon molecules of pyruvate.
- One glucose molecule produces four ATP, two NADH, and two pyruvate molecules during glycolysis.
- The net products of this process are two molecules of ATP, since four molecules of ATP are produced and 2 ATP molecul;es are used, and two molecules of NADH.
